TEXTILE-BOBBIN.

Specification of Letters Patent.

Application filed April 5, 1919. Serial No. 287,746.

citizen of the United States, residing at Elkhart, county of Elkhart, and State of Indiana, have invented certain new and useful Improvements in Textile-Bobbins, of

which the following is a specification.

The invention relatesto improvements in textile bobbins, and aims to produce as a new article of manufacture a #:xtile bobbin made of metal as distinguished from the ordinary wooden bobbins which are in general use in textile establishments for the storage of yarns and the like.

While the initial cost of wooden bobbins may be relatively low, it is to be noted that the upkeep of the same is comparatively high. They break very frequently when v roughly handled, and if broken are entirely useless. They also have the peculiarity of absorbing oils or other liquids, and while not excessive in 'weight, must be made rather clumsy in order to provide for suflicient strength and stiffness. It is also a disadvantage of wooden bobbins that they are inflammable and that their weight is far from being uniform, consequently it is difiicult to ascertain with exactness the weight of the yarn stored on the bobbin.

It is an object of the present invention to manufacture a bobbin in which these disad-' vantages are avoided. The metal bobbins can not only be made at a low initial cost, but they also require only a very small additional expenditure for the upkeep.

It is furthermore an object to provide a bobbin which does not break as easily as a wooden'bobbin, which has smoother edges than the ordinary wooden bobbin, and which therefore does not readily catch the strands of yarn to be stored on the bobbin.

It is furthermore an object of the invention to construct a bobbin having flange plates which when bent can easily be restored to their original condition or which can be replaced, thereby eliminatin the great waste which could not be avoi ed in the use of wooden bobbins.

It is also an object of this invention .to provide a metal bobbin which with the same diameter of flange plate will permit the use of a smaller barrel without decrease in the strength'or stiffness of the bobbin, so that on a metal bobbin of this size a greater amount of yarn can be wound than on a wooden bobbin.

It is furthermore an object of the invention to provide a metal bobbin of this character with driving lugsflwhich may be readily replaced whenever they become worn or damaged, and which facilitate the counterbalancing of the two flange plates of the bobbin.

It is obvious also that in metal bobbins greater uniformity of weight is attainable when these bobbins are made on a large scale, and that the dangers of combustion of the bobbins are avoided. With these and other objects in view, the IIIVBl'ItlOII is described in the following specificat on, reference being had to the ac'-' companylng drawing, wherein:

Flgure 1 is a perspective view of a metal bobbin of this kind; 2

Fig. 2 is a vertical central section through a pprtion of a barrel and a flange plate;

1g. 3 is asectional view of one of the spokes of the flange plate;

Fig. 4 is a sectional view of a brace connected'with the flange plate, and i Fig. 5 illustrates a front elevation of a modified flange plate.

'The bobbin comprises abarrel 1 and flange plates 2, secured to the barrel near the ends thereof and in planes at right angles to the axis of the barrel. The barrel is formed, as may be seen from Figs. 1 and 2, as a tubular member having near its ends wooden bearing plugs 3, inserted in the barrel and held therein by pins or the like.v It is obvious that these .wooden bearings can readily be exchanged at small expense when they become worn.

For the purpose of increasing the stren h of the flange plates, the latter are provi ed with reinforcing portions which extend in the form of a bead 4 along the circumferential edge of the flange plate 2, and also with spo es 5, which connect the marginal portions of the flange plates with the central portion of the same. From Fig. 3 it will be noticed that the metal spokes 5 are reinforced by bending the same longitudinally, providing a radial curvature 6 and longitudinal marginal bends 7. Thebeads 4 of the flange plates are turned outwardly, leaving the entire space between the two flange plates free for the storage of yarn or Patented Feb. 15, 921.

. through like material, and owin to the rounded bead, the danger of catching thread or yarn on the circumference of the flange plates is eliminated. v

For further strengthening the flange plates 2 the latter are provided, in alternation with the spokes 5, with braces 8, which also are preferably made integral with the flange plates, and which extend angularly from the planes defined b the plates. The inner en s of these braces 8 are shaped into hook form, as indicated at 9, and the hooks are inserted into slots 10 of hub disks 11, which are fixed to the outer ends of the barrels 1 of the bobbin. From Fig- 2 it will be noted that thehub disks are made of stock which is heavier than the stock of the barrel or flantfe plates, and these hub disks are inserte by means of their shoulder portions 12 between cylindri cal extensions 13 of the flange plates and between angular marginal portions 14 at the endsof the barrels 1. The main portion of the braces 8, which are also made integral with the flange plates,

entire structure.

Driving lugs 15, in the form of bellshaped strips, are secured at their outer ends to the marginal portions of the flange plates at 16, while -the1r inner or raised ends are connected to the marginal portions of the hub .disk 11 by means of rivets 17 or the like. These driving lugs are provided with suitable openings 18, into which the driving member of the spinning machine or the like may be inserted. While, according to Fig. 1, each of the flange plates-has a single drivingrlug 15, the modified end flangeshown 1n ig. 5 illustrates an arrangement wherein two of these driving In 15 are provided on the same face of the ange plate. From Fig. 1 it will also have to be noted that the two flange plates at the ends of the bobbin are angularly offset with respect to each other, so that axial planes placed centrally the spokes and braces of one flange plate will pass centrally through the braces and spokes respectively of the other flange plate. In this manner the entire weight of the flange plates is uniformly distributed over the bobbin structure, and the exact balance which is necessary in the high speed rotation of these implements. is carefully maintained. This maintenance may be on hanced by the provision of two driving lugs diametrically opposite each other in each flange plate; the driving lugs on one flange plate, however, being oflset angularly with respect to the drivmg lugs of the other flange plate, as indicated in Fig. 5.

the spokes 5 of is bent into circular shape, as shown in Fig. 4, to strengthen the the ends of the barrel, flange plates secured to the barrel, and braces secured to said flange plates and connected with said hub disks. I

2. As an article of manufacture, a textile bin, comprising a metal barrel, hub disks at the ends of the barrel, flange plates on said barrel intermediate said disks, and braces, the hub disks being provided with slots and the braces having terminal hook portions enterin said slots.

3. As an artic e of manufacture, a textile bobbin, comprising a tubular metal barrel having marginal angular portions, flange plates provided with a cylindrical flange portion seated on said barrel, hub disks secured to said barrel between said mar 'nal angular portion and said cylindrical ange portion and elements connecting said flange plates and hub disks.

4.- As an article of manufacture, a' textile bobbin, comprising a barrel and metal end flange plates having s okes alternating with braces, the spokes and braces in one flange plate being an ularly offset with respect to tllie spokes an braces in the other flange ate.

P 5. As an article of manufacture, a textile bobbin, comprising a barrel and metal end braces, the flange plates being so disposed with respect to each other that axial planes placed centrally through the spokes and braces of one flange through the braces an spokes respectively of the other flange plate.

6. A textile bobbin, comprising a metal barrel having marginal angular portions, flan plates consisting of radialarms and a bea ed rim seated on said barrel,hub disks of heavier stock than the flange plates mounted on theends of the barrel, said flange plates being provided with brace members which enter slots in said hub disks.

7. A textile bobbin, comprising a metal barrel having marginal angular portions, flange plates provided flange portion seated on said barrel, said flange plates being provided with integral radial arms extending from the cylindrlcal portion to the circumferential portion of the plate and being provided with braces integral cplate pass centrallywith a cylindrical 1 with the marginal portion of the flange plate, I
